To all whom it magro-acera:

Be ittknownthat we, BENJAMIN` B. TILT:` and. Jamais Slimmer, both` of Roxbury, i in i the county of` Norfolk and State of Massachusetts,have invented 'a EneW-and useful yiin provement-irr machinery forfdressingor tinishfing Worstechor other threads-or cords or removing therefrom the fibers which usually extend i in;i lateral directions from their sur- 101, faces after. thef Spinnin-gcV process--sV is` com-` piet-ed,l `the said improved mechanism bei-ng represented, in the accompanying 1 dra-Wings, and described in Ythe following specificati which taken together constituteaa` full 7 andx` exact description,there-of;` y

A bell crank I of the shaft G has a connecting rod K extending therefrom to the rubber or roller frame L, to which said connecting rod `is jointed in a similar manner. This rubber or roller frame consists of a rectangular frame of Wood or metal I, Figs. l, '3, the `ends of Which are supported in suitable guides or grooves formed in pieces M, M, applied to the frame A, soV as to admitfof a reciprocating rectilinear movement of the frame L in a longitudinal direction.` The frame L supports any proper number of transverse rollers ror cylinders N, N, N, Which are sustained in positionbyand revolve in vertical standards or pieces O,- O,O, Figs.l l, 23,' 3, applied ifto the,` said frames Guide pl atesk lP, Q, are uerrangedvertieally upon transverse bars 50 R; Rggvhachfare secured upon the top `rails of` the vmain frame A, as` Vseen, in the drawings, thesaid guide plates consisting o fpieces of meta-1,1; having a; numberof S holes` boredr through tliem,just,belovvtheir upper;` edges.

' Any suitable,mechanism may` be f arranged to regulate the lilling of the receiving bobbins. That which is here adopted consists lo() of a frame 7c, arranged vertically and properly secured so as to slide back and forth transversely. This frame is elevated in rear of the receiving bobbins, or between the same and the guide plate Q.. Fig. 6, exhibits a View of this frame, as detached from the apparatus. Each of the threads is passed through a small metallic eye Z inserted in the side of one of the upright bars m, me, of

the frame. From this eye it proceeds to the bobbin on which it is to be Wound. The frame s is moved in a lateral direct-ion or in a plane parallel to the axes of the bobbins, by a bent lever a, 0, y) whose fulcrum is at 0 and whose upper' end n is jointed to the frame or to an arm g extending therefrom, and whose lower end p is b-ent as seen in Fig. 5, and rests against the edge of periphery of a cam 1 situated upon a horizontal shaft. s. The revolution of this cam actuates the lever or pushes the frame 7c forward laterally. The cam shaft s is caused to revolve by an endless screw t which is fixed on the end of the shaft u of the drum Y, and enters into or engages with the teeth of a spur gear wheel u', fixed upon the shaft s. The frame if: is drawn back by the action of a weight o, appended to a cord au, the said cord passing over a pulley and being connected to a stud g/ of the frame v, as seen in Fig. l.

The surface of each of the rollers N, N, N, should be draw filed, or roughened in any other proper manner, as it is by the peculiar operation of the threads when wound over these rollers in connection with the roughened surfaces of said rollers, that the filaments of the threads are removed. The draw-filing prevents slipping of the filaments when they are grasped or held between the thread and surface of the roller and torn away from the thread by the combined action of the thread and roller. "While the threads are passing over the space between the guide plates P, Q, the rubber frame is put in a rapid reciprocating rectilinear motion, and as each thread is wound once about or around each successive roller, the thread is alternately un-V wound from and wound upon each of the said rollers. Now as the thread departs from the roller, the filaments which stand out laterally from the thread are caught between the part -of the thread which is being wound on the roller and the surface of the roller and are there grasped and firmly held, while that part of the thread to which they are attached departs from the roller, the consequence of which is the separation or tearing away of the said .filaments from the part of the thread to which they are connected. As each roller performs such an operation to a greater or less degree, each thread after it has left the guide Q in its passage toward the receiving bobbins will be found to have been completely or sufficiently divested of all the filaments which originally projected therefrom, and to possess a peculiar wiry feel or finish. From what has been stated above, the modeof dressing threads or cords will be readily comprehended. Though the peculiar effect herein before set forth of rollers or a rubber frame in removing the filaments of a thread is well known, as the same has been in common use for some considerable time, yet as such a rubber frame has only been a hand instrument or tool operated by man nal labor, while the threads or cords to be finished have been stretched between two fixed points, the amount of work accoms plished by it has been very limited.

By the arrangement o-f frames of delivery and receiving bobbins, guides, and rubber frame, operating together as an automatic machine in the manner as before explained an immense amount of labor is saved and the threads are dressed in a much more regular and thorough manner, than is the case where the process is accomplished by the hand of the operative.

Having thus set forth the nature and principles of our improvements by which they may be distinguished from others of like character we shall now proceed to point out that which we claim to be our invention.

Ve claim- The combination of the rubber frame with the delivery and receiving bobbins, also the combination of theV guide plates with the said rubber frame and bobbins, the whole being arranged together and operating substantially as herein above explained.

In testimony that the foregoing is a true description of our said invention and improvements, we have hereto set our signatures this fifteenth day of J une in the year eighteen hundred and forty three.
